I have a Demand Products CNC foam cutting "Twister" with a 5 foot hot wire. I have having trouble with my controller, but if it goes bad, it will cost $4,000-$5,000 to replace the controller. Do you know of a MUCH cheaper alternative controler than will operate my "Twister"? Thanks.

Existe algún material biodegradable que yo pueda cortar con la ayuda de este software y una cncfoam? Estoy muy interesado. Por favor iluminenme

excelente trabalho! continue

Hi Keith, I have just finished building the rig you designed, and all is working well, however looking at the software none obviously allows cutting the wing profile from the trailing edge. Wing Designer is nice with a very simple clear interface, but I can't see how you would do this, with this program. Does DevWing Foam 2 allow this option? I would prefer cutting from the trailing edge and ending at the trailing edge so the foam core can act as a mold to make a fiberglass covered wing. There would be no entry/exit cut at the leading edge. Thanks for your very comprehensive videos which are well paced and easy to watch.

I have had a foam board needle cutter CNC (TimSav) for a few years and it works great but I am now looking for something similar to cut foam and really like your design as it uses a lot of the same electronics as the TimSav. I would prefer though to have the frame use extruded aluminum and 3dprinted parts rather than MDF. I will look through your builders galley but if I find one how do I contact the builder for details of their design?

Hello, can I use this program to cut letters, thank you

Hi Keith, congratulations for excellent project! I have a question/issue. I have built a CNC foam cutter, and it runs fine, except that when cutting the wing, the wire seems to jump up or down by one step on both sides, i.e. I get a correctly cut wing which may have a raised section of a few mm to a about 1 cm. The problem is not in GRBL files, because it occurs in different spots when repeating the same cut. It also not a problem of misstep, because it occurs on both sides and the wire returns back to the correct position. Shielding issue would not produce such a thing either. Any suggestions as to where to look for the problem?

Good morning, I wanted to tell you about my problem and if you can tell me what I did wrong. I set up a wire-cut CNC with a rotary table. I have ramps 1.4 with the xyzu firmware, I have 10 limit switches connected in series. For minimum and maximum in each of the five axes. I use the latest version of your software for xyzu. Start the program, run home for all axes, this works perfectly. I start cutting out blocks of foan to later use a gcode file. X,Y,U,V = 0 is at the front of the CNC and below (my home) Ex.: I move X,U = 200mm (absolute coordinates) to the bottom without problems. then (by mistake) I ask it to move forward (towards home) 250mm and it collides with the limit switches and the structure. And I have to turn everything off so it doesn't break. What did I forget to configure? Because the limit switches work perfectly when they hit home. Thanks and sorry for the inconvenience

Hi Keith, finally getting around to building a cutter after way to long. Your new version and Bigtreetech board is going well so I started looking at Basic Cad/Cam options to begin with. Not sure if you have looked yet but GrblGru has several recent videos on playing with foam cutting using his simulation software. Using one of his prebuilt models and doing a single axis relabel it exports G Code that your GRBL Hotwire software seems to handle. More playing yet on some finer details and post processing settings I suspect but worthy of a look as it is free/donate software as well.

Great thank you Keith all the best from Hookey tootgarook Australia enjoy life while your yong😊😊

If my wire has a diameter of 4mm, should i specify a Kerf width of 4mm or 2mm?

Hi Keith, I am very happy to see that you continue to hobby and your last announcement was especially for making KZbin videos. I was worried your health was struggling so much you could not do the things you love anymore. Your video also reminded me that I have a CNC Hotwire cutter that’s finished for 98% and that I need to put my CNC machine together after moving last year😅

Hello mr. Keith, i am from Eritrea,I m currently working on 4 axis with arduino mega and ramp 1.4, i couldn't find any contact details in your site. I am facing problem with the A axis limit switch as you mentioned in your site post,it one of the common ones. If you read this please let me know how can i contact you, or if anyone got the contact you are welcome to share it, thank you

Senational Keith! Thank you for sharing all of this with all of us. Yesterday I received the MKS and practically everything is there, just the cable that doesn't come with the mesh, so I'm going to look for one with the mesh.

Great work Keith 👍 It seams to work out very good with a needle cutter. I my self cut out foam parts in an 10 W diod laser.

Nice, that's slick! From where did you purchase the extrusion attachments and connectors or did you draw some of those yourself

WOW, that looks like it works really well. Since it's out of extrusions it should scale up really easy. Nice.

🔝🔝🔝

What is the largest aircraft can you make on your 3 d printer many thanks

Life keeps getting in the way. Trying to get back to getting it working again. What board and version would you pick at this time (8 months later)? I know you like dev but what other programs can be used with your recommended board to make wings and plane profiles? Here we are years down the road and I still don't have it running! Thanks for the video and help.

Great video and 2 very nice planes you have built. Thanks for sharing. Greetings from Norway

At 6:10 there is movement of the dog axis! I was getting worried!

Hi Keith. Nice maiden. Great to see another vid from you. I still can't thank you enough for all the work you did on the CNC foam cutter

Brill Keith no walk of shame

Hey Kieth you good Long time no see

keith i have a sugestion, can you resize the Monitor list(the box who list the commands) we lose at least 4 lines because the box doesnt fit at the screen , and i'm using 1980x1024 resolution.

So this will cut foam board as well??

Hi, DXFtoDAT exe from your link does not work, was it updated since your video? Thank you

Hello Keith, what is the minimum monitor size to work with the grbl 5x software? I want to use a 15 inches monitor with touch screen, do you know if fit the screen software on a 15 inches monitor?

I flashed the firmware using Mac via avrdude and things seems to be working fine. Is there a way to reverse the direction of the motors without without modifying the code directly. Maybe a gcode value

Hi Keith! Hope you are ok, and thanks for all the work you share with us! I know i'm 3 years behind with this question, how do you get the g code out of Jedicut, and where does it store the file, scratching my head here!? I have a Devwing foam2 license, but this .dat shit anoys me, i'm using Vectric and SW and those programs does not help me with .dat . Hope you have a nice summer with good weather and much flying, Regards, Peter, Sweden

Have you heard about GrblGru? A wing creator was added for foam cutting. This software offers some nice features like creating cuts from svg or dxf data. With that you can create custom cutouts for example for fuselage walls where the wingprofile must be cut out. I can only recommend it!

how can i downlord software arduino or mega, thank for this video.

Thank you so much. Great job. Seems that there is an error in the description of the input for A-Min endstops, using a 2560 and Ramps 1.4 I'm sure of my switch as it works if I put it into an other "channel", i can see it switching like a charm. For A-Min I tried D49 and not working. It seems that the preset are fixed for D42 instead. By the way would it be possible to upload the source of the Mega2560 code, it would enable us to change in/out depending on our 'old wiring' For the software some color (ie especially for axis) would be nice, it would enable to 3dprint part of each axis with a color and refer to this color in the sofware, the no more error in moving an axis instead of an other. PS : if you need french translation do not hesitate, some of the implemented one are badly translated :-(

Thank you :-)

Thanks Keith. Looks like i have another project to build 🙂

from the schematics i've seen for the RAMPS board it looks like you can only have up to 5A for the circuit that powers the stepper motors. Is there a way to increase this?

Yes thats sad, it was a beautiful build and the vc10 is eye candy when its just sitting there. This must always be an issue with working models, hours and hours spent put into recreating authentic detail when all that can be wiped out in a second. There is another vid on yt of a flying model vc10. Here the props are not in the cowling so can be bigger.

What can you do if the PDF is just an embedded image and wont ungroup into different components?
